Just recently I have been getting a box pop up containing the message "Error 30001". I Googled for "Error 30001" and found that many people are having this problem with all different kinds of programs, systems and equipment. Naturally, a certain website offered to cure this ERROR and if you try the FREE scan it will find hundreds of faults with your entire system and then offer to remove/cure them for a price!!!! Being aware of this web site and refusing their offer to cure my 248 faults (which no other program can find), I checked my system and found that it was a Video downloading Tool bar which was working unknown in the background and couldn't get through to a target Internet site because I had it BLOCKED in my firewall, thus resulting in the pop-up message "Error 30001". Switching the Tool bar OFF or opening the Firewall when the Tool bar is required removes the "Error 30001" and I just wondered how many of the other people in the Googled list had been caught out by the FREE SCAN and could have cured this fault simply by checking their programs and/or Firewall settings? Possibly worth remembering if you get an Error Message in the future????
